NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 683,778, dated October 1, 1901. Application filed February 7, 1901. Serial No. 46,377. (No model-l To @ZZ z'ulwnt t may concern:

Be it known that l, PETER LESCH, a citizen of the United States, and a resident of the city of New York, borough of Manhattan. in the county and State of New York, have invented a new and Improved Non-Rellable Bottle, of which the following is a full, clear, and exact description.

In carrying out my invention I employ a novel arrangement of valve devices and auxiliary parts, together with an improved ioat in the form of a buoyant bulb whose function it is to close the valve against the .inliowing liquor should the bottle be inverted and the air exhausted therefrom in the effort to refill the bottle. Furthermore, I give to the bottlc-neck and its closure devices a form to defeat an attempt to dislodge the said closure devices by means of a wire or the like.

The invention consists of novel features and parts and combinations of the same,as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of .reference indicate corresponding parts in all the views.

Figure l is a central sectional elevation of a bottle-neck and inclosure embodying my invention. Fig. 2 is a similar section showing the bottle in inverted position, and Figs. 3, 4, and 5 are separate perspective views of different parts which will be hereinafter more particularly described. l

Formed integrally with the bottle-neck A and the bottle-body A is a contracted portion B,provided with abeveled seat b, adapted to receive the correspondingly-formed portion c of a valve C. As particularly shown in Fig. 4, the valve C is provided with a rigid upwardly-projecting hollow stem c and with a pendant formed with grooves c2 to permit the outflow of the liquid,the lower end ofthe pendant being solid and forming an end weight, which tends to return the valve to its seat. In connection with the solid pendant or other weight which maybe employed to insure a seating of the valafe I provide further means for normally maintaining the valve in closed position, particularly when the bottle is in inverted position. These means consist of a coiled spring E, inclosed bythe stem c', which spring bears at one end against the closed lower end of the hollow stem c/ and shuts at the other end against a shoulder e', formed on an independent rod e, the upper end of which is received in a central recess in the lower portion of a guard-cap F. The valve is held to its seat until the force of the spring is overcome by the pressure of the liquid dowing from the partly-inverted bottle.

On the hollow stem c' of the valve C is fitted a buoyant bulb D,haviug a central tube d sliding on the stem c. This buoyant bulb D will come into action if it be attempted to refill the inverted bottle after exhausting the air, for the in flowing liquid will ioat the bulb and will thereby raise the valve C to its seat. The bulb is free to slide relatively to the valve, so that the valve cannot be raised from its seat by pouring liquid into the neck when the bottle is in its normal upright position. y

The guard-cap F is cylindrical in form, is open at the top and closed at the b ottom, and is provided with side openings f', through which the liquid contents of the bottle may flow out-of the open top. As clearly shown in Fig. 3, the guard-cap F is furthermore formed with a peripheral groove f2, designed to register with a similar groove ct in the bottle-neck. In these grooves a number of bow-sprin gs G are engaged, which are sprung into place in an obvious manner when placing the guard-cap Fin the neck. The springs engage both grooves and hold the guard-cap in place. The bottle-neck A is formed with an annular recess a', producing an annular shoulder a2 adjacent to the outlet-openingsf of the guard-cap F, so that a wire inserted through one of the openings f will be arrested by the shoulder ce2. The neck A projects above the guard-cap F a sufficient distance to receive the usual stopper H.

Having thus described my invent-ion, I claim as new and desire to secure by Letters Patent* l. A means for preventing the refilling of bottles comprising a valve; a stem above the valve, and a iioat having sliding movement on the stem.

2. In devices for preventing the refilling ICO of bottles, the combination of a valve having an uinwardly-projecting stem, a cap above the stern, a rod intermediate of the stem'and cap, and a buoyant float having sliding movement on the stem.

3. In devices for preventing the refilling of bottles, the combination of a bottle having a neck with an integral contracted portion; a valve therein, having an upwardly-projecting stem; a rod teleseoping the stem; a cap above the rod; and a buoyant oat having sliding movement on the stem.

4. In devices for preventing the refilling of bottles, the combination of a bottle having a neck with a contracted portion; a valve therein having an upwardly-projecting stem; a spring-acted rod telesooping the stem; a cap above the rod; and a buoyant float having sliding movement on the valve-stein.

5. The combination with a bottle having a neck with an integral contracted portion formed with a valve-seat, a valve adapted to the said seat, the valve having a pendent portion and a hollow stem rising from the upper end, a buoyant bulb having a tubular center fitting the valve-stem, a rod guiding the valve-stein, a cap above the rod, and a spring within the valve-stem, the lower end of the spring having a bearing at the base of the valve-stem and abutting at its upper end on the rod.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. y
